Gas reservoir in the 8 member of Shihezi Formation in upper Paleozoic in Ordos basin is a typical lithologic reservoir with low porosity and low-permeability.The physical property of gas reservoir and gas-bearing quality is horizontally anisotropic.It is difficult to predict the sand reservoir distribution by means of normal post-stack technique.Based on pre-stack data,we used seismic trace gather,close-medium-far superimposed section,pre-stack angle domain hydrocarbon detection and elastic parameter inversion to predict the gas\|bearing quality in the 8 Member of Shihezi Formation,Sulige gas field.The practical test has proved that it is effective.
